Mitosis Quiz

What is the main purpose of mitosis?

• To carry out daily cell functions

• To make identical body cells

• To organize DNA into chromosomes

• To produce sperm and egg cells

Answer explanation

The main purpose of mitosis is to make identical body cells.

What is the result of mitosis?

• Different cells

• Protein and DNA

• Identical cells

• Sperm and egg cells

Answer explanation

Mitosis results in the formation of identical cells.

What is the stage where chromosomes line up in the middle of the cell?

• Metaphase

• Prophase

• Anaphase

• Telophase

Answer explanation

During metaphase, chromosomes line up in the middle of the cell. This ensures proper separation during cell division.

What is the function of spindles in mitosis?

• To carry out daily cell functions

• To produce sperm and egg cells

• To organize DNA into chromosomes

• To help move the chromosomes to the ends

Answer explanation

Spindles in mitosis help move the chromosomes to the ends.

What is the final stage of mitosis?

• Metaphase

• Prophase

• Anaphase

• Telophase

Answer explanation

The final stage of mitosis is Telophase. During Telophase, the chromosomes reach the opposite poles of the cell and a new nuclear envelope forms around each set of chromosomes.

What is the process responsible for the final separation into two cells?

• Prophase

• Cytokinesis

• Anaphase

• Metaphase

Answer explanation

Cytokinesis is the process responsible for the final separation into two cells. It occurs after the completion of mitosis and ensures the proper distribution of genetic material into each daughter cell.

What is the result of duplicating the 46 chromosomes in interphase?

• 46 chromosomes and 92 chromatids

• 92 chromosomes and 92 chromatids

• 92 chromosomes and 46 chromatids

• 46 chromosomes and 46 chromatids

Answer explanation

Duplicating the 46 chromosomes in interphase results in 46 chromosomes and 92 chromatids. This is the correct choice.

Why is understanding mitosis important for cancer research?

• To understand uncontrolled cell growth

• To prevent the formation of chromosomes

• To understand how growth and repair happens

• To carry out daily cell functions

Answer explanation

Understanding mitosis is important for cancer research because it helps us understand uncontrolled cell growth, a key characteristic of cancer.
